  However, in the holder of Patent Document 1, it is necessary to push the locking protrusions protruding from both ends of the bottom rail into the holding pieces, so that when operated alone, only one of them is locked when the product width is large. The protrusion cannot be held between the holding pieces. Therefore, when only one side is held, there is a problem that the lower end of the blind is cantilevered and the shielding material is inclined and wrinkled. In particular, in the case of a blind that is biased in the direction in which the shielding material rises without a stopper, such as a roll screen, the inclination becomes large, and an unreasonable force acts on the blind, which is not preferable. .

  The present invention has been made in view of such a problem, and an object of the present invention is to provide a blind lower fixing structure capable of easily fixing the lower part of the blind to the fixing surface without applying an excessive force to the blind. .

In order to achieve the above-described object, the blind lower fixing structure according to the first aspect of the present invention is such that the receiving portion is provided on the lower support member provided at the lower part of the blind shielding material and is held on the fixing surface such as the window frame. And the holding part is composed of a base fixed to the fixed surface and a movable member that can be moved relative to the base and can be engaged, and the movable member and the base are not engaged with each other. In this state, the receiving portion can be locked to the holding portion, and when the receiving portion is locked to the holding portion, the shielding material is temporarily fixed so that it cannot be raised. Doo is the Rukoto engaged, the receiving portion, characterized in that it is unlocking impossible restrained in the holder.

  According to a second aspect of the present invention, in the first aspect of the present invention, when the upper surface or the side surface of the movable member is pressed, the engagement between the movable member and the base is released, and the movable member can move relative to the base. Features.

  According to the present invention, when the movable member and the base are not engaged, the blind member is locked to the movable member or the base of the holding portion, thereby enabling temporary fixing. When the blind is fixed or when the blind is released, the receiving portion is temporarily fixed to the holding portion to prevent the blind from rising carelessly or to prevent the blind from tilting. By moving the movable member from the temporarily fixed state and engaging with the base, the receiving portion is restrained by the holding portion so as not to be unlocked, and the lower portion of the blind can be securely fixed to the fixed surface.

  According to the invention described in claim 2, since the engagement between the movable member and the base can be released by pressing the upper surface or the side surface of the movable member, it can be released with one hand. Mainly, the load from the receiving part can be received by the locking force of the holding part, and there is no need to restrain the receiving part by the engaging force between the base and the movable member. It is not necessary to strengthen the movable member, so that the movable member can be easily engaged with and disengaged from the base.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is an overall front view showing a blind to which a blind lower fixing structure according to an embodiment of the present invention is applied.

  As the blind, any blind such as a horizontal blind, a pleated screen, or a roman shade can be used, but in this example, a case where it is applied to a roll screen is shown.

  On the roll screen 10, an upper part of a screen 12 as a shielding material is attached to a take-up pipe 14 so that it can be wound and unwound. ing.

  The weight bar 16 is provided with catchers 16a as receiving portions at both ends thereof, and the catcher 16a includes a ring portion 16b that forms a closed cross-sectional space.

  A holding portion 20 is fixed to a fixed surface 18 such as a window frame corresponding to each of the catchers 16a. As shown in FIGS. 3 to 6, each holding portion 20 is composed of two parts, a base 22 and a movable member 24.

  The base 22 is fixed to the fixed surface 18 by a set screw or the like so as not to move, while the movable member 24 is attached so as to be slidable with respect to the base 22 and not detached from the base 22.

  More specifically, an elastic piece 22b is formed by cutting out at the bottom 22a of the base 22, and a stopper 22c protruding upward is formed at the tip of the elastic piece 22b. Further, the base 22 has a locking portion 22d formed on the top thereof, and this locking portion 22d can penetrate the ring portion 16b of the catcher 16a, and the ring portion 16b can be locked to the locking portion 22d. It has become.

  One movable member 24 is formed with a slide portion 24a that covers a side portion and an upper portion of the bottom portion 22a, and an opening 24b is formed in the slide portion 24a. Further, the movable member 24 is formed with an engagement surface 24c erected upward from the middle of the slide portion 24a.

  Further, a push button portion 24d that can be elastically displaced by cutting is formed on the upper surface or side surface of the movable member 24, and a gap 24e is formed between the push button portion 24d and a portion adjacent to the push button portion 24d. Is formed.

  The stopper portion 22c of the base 22 can be locked to both the gap 24e and the opening 24b of the movable member 24, and the slide portion 24a of the movable member 24 slides with respect to the bottom portion 22a of the base 22 in the range between them. It is possible. When the stopper portion 22c of the base 22 is locked to the opening 24b of the movable member 24, the engagement surface 24c of the slide portion 24a and the locking portion 22d of the base 22 are separated from each other, and upward between them. While an open space is formed (FIGS. 3B, 4B, and 5B), when the stopper portion 22c is locked in the gap 24e of the movable member 24, the movable member 24 and the base 22 are engaged, and the front end of the locking portion 22d of the base 22 is brought into contact with the engaging surface 24c of the slide portion 24a, so that a closed section space is formed below the locking portion 22d (see FIG. 3 (a), 4 (a), and 5 (a)).

  In the lower fixing structure of the blind configured as described above, when the lower part of the screen 12 of the roll screen 10 is fixed to the fixing surface 18 such as a window frame, first, the movable member 24 of the holding unit 20 is slid. The engagement surface 24c and the locking portion 22d are kept apart.

  In this state, the ring portion 16b of the catcher 16a is hooked on the locking portion 22d and locked. Since this locking operation does not require a particularly large force or difficult operation, the catchers 16a on both sides can be hooked on the locking portions 22d of the holding portions 20 on both sides almost simultaneously. Thus, the roll screen 10 can be temporarily fixed to the holding unit 20 without being tilted.

  Next, when the movable member 24 is slid to approach the base 22, the stopper portion 22c is locked to the opening 24b, and the movable member 24 and the base 22 are engaged. Since the engaging surface 24c of the movable member 24 and the locking portion 22d are in contact with each other to form a closed space, the ring portion 16b of the catcher 16a cannot be detached from the locking portion 22d, and the holding portion 20 Restrained by At this time, the lower part of the screen 12 of the roll screen 10 can be restrained by the holding part 20 without operating the stopper built in the winding pipe 14, and by the urging force by the spring built in the winding pipe 14. Since the screen 12 is pulled in the winding direction of the winding pipe 14, the screen 12 can be held in a tensioned state.

  Thus, the lower end of the roll screen 10 can be fixed to the fixing surface 18 such as a window frame in a state where the screen 12 is lowered. For example, when a blind such as a roll screen 10 is used as a blindfold or partition for a storage unit or the like and the screen 12 is always lowered and used, the screen 12 may rise carelessly, or the screen 12 may be blown by an air conditioner or the like. The roll screen 10 can be fixed without being beaten.

  Conversely, when it is desired to raise the screen 12 of the roll screen 10, the push button portion 24d is pressed downward, the elastic piece portion 22b of the base 22 is pushed downward at the lower end portion of the push button portion 24d, and the stopper portion The locking of the opening 22b of 22c is released, and the movable member 24 is pulled out from the base 22. At this time, since the catcher 16a maintains the state of being caught by the locking portion 22d, it is possible to prevent the screen 12 from rapidly rising due to the urging force of the spring built in the winding pipe 14. After moving the movable members 24 of all the holding parts 20 away from the base 22, hold the weight bar 16 by hand, remove each catcher 16a from the locking part 22d, and gently release the hand. As a result, the screen 12 is automatically wound around the winding pipe 14 and is raised.

  As described above, since the catcher 16a can be temporarily fixed by the locking portion 22d of the base 22, the roll screen 10 cannot be fixed even when the lower portion of the roll screen 10 is fixed or released. It can be done easily without force.

  No direct clamping force or the like is applied to the catcher 16a between the movable member 24 and the base 22, and the blind load from the catcher 16a is received by the locking portion 22d. It is not necessary to increase the engagement force between the two. Therefore, the movable member 24 can be easily engaged with or disengaged from the base 22 and can be switched manually by simply pressing the push button portion 24d of the movable member 24.

  In this embodiment, the locking portion 22d for temporarily fixing is formed on the base 22. However, the present invention is not limited to this, and it may be formed on the movable member 24 side.
